Armourflow™ is an advanced geocomposite drainage board used to protect waterproofing coatings and efficiently transport water into the drainage systems at the base of retaining walls to prevent hydrostatic pressure build up.
Armourflow is comprised of a dimpled high crush resistant HDPE core with a highly permeable geotextile filter bonded onto one side to provide a drainage sheet. It is commonly used behind basement and retaining walls to collect and filter water ingressing from backfill soils. Armourflow also protects the waterproofing liner from damage when the backfill soil is being placed.
Due to Armourflow’s lightweight structure, it can often be used to replace conventional mineral drainage aggregate, saving time and money. It is also quick and easy to install and doesn’t require heavy machinery.
